Application filed February 3, 1898. Serial No. 668,917. (No model.)

To ctZZ whom it may concern:

Be it known that I, GEORGE L. RoBY, a citizen of the United States, residing in Grand Haven, in the county of Ottawa and State of Michigan, have invented certain new and useful Improvements in I-Iand-Oultivators, of which the following is a full and complete description, reference being had to the accompanying drawings.

My invention relates to hand-cultivators; and it consists of an improved form of construction,a new manner of adjusting the culti- 1gaicng-tooth thereomand a new form of hand Figure 1 is a perspective view. Fig. 2 is a detailed view of the lower end of the frame. Fig. 3 is a detailed view of the parts employed in clamping the cultivating-tooth thereon. Fig. 4 is a detailed view of the parts employed in clamping the cultivating-tooth. Fig. '5 is a sectional view of the handhold. Fig. 6 is a sectional View of the aXle and manner of binding certain members together.

Similar letters refer to similar parts throughout the different views.

In constructing an implement of this class it is of the utmost importance that while it should be light and easily handled it should be Very stiff and inflexible. To attain these desired qualities, I have made the frame in that part where it has heretofore been constructed the weakest of a double-truss form, which I have joined to a casting of peculiar form; The truss members B B B B have holes provided in each end thereof and through which a bolt is passed at A and A thereby binding them fast to the casting A. The other hole in each piece B B B B is passed over a reduced section of the spindle B Fig. 6, thereby completing the truss formation.

In order to properly joint the lower part of the frame to the wooden handles F F, forming a part thereof, a seat is formed at F to receive the same and bolts passed through the parts at A and A.

At the lower end the standard A is divided into two members G G, leaving a slot for the passage of a clamping-bolt to hold the cultivating-tooth in place. The back edge of these members G G are notched at the corners H, and corresponding lugs or projections I I of the clampingwasher I fit therein, preventing any slip of the tooth when in use. In connection therewith there is used a tooth-engaging plate J, engaging with the face of the members G G. The shovel or cultivator tooth D having two holes J and K, the bolt L is passed through J 2 and the pin K through K. The whole combination when placed upon the members G G (which can be done without dis- 6o connecting the parts) are quickly and firmly clamped by tightening the nut on the bolt L.

In a tool to be propelled by hand-power it is also of importance that the means of connecting the machine to the person should be of a form to secure the greatest ease and convenience. In my invention I secure this result by employing a metallic member M, molded to exactly fit the hand when closed as in use, and so distributes the pressure over the interior thereof and reduces the consequent friction and pain otherwise present. The part M is made of hollow or tubular form, and from each end thereof there are two extended parts 0 and N, formed integral therewith,which pass to opposite sides of the handle F and are clamped thereto by the bolt P, passing through the parts .N, O, and F, as shown in Fig. 5.

.Having described my invention, I claim and 8c desire toprotect by Letters Patent 1. In a cultivator the combination with the main frame, of a depth-regulating wheel, and a truss construction connecting said wheel with the main frame, comprising two arms on a truss construction for connecting said wheel to the frame, comprising two arms on each side of the wheel having their forward ends connected to the wheel-axle and their rear ends connected to said frame at separated points in different horizontal planes, substan- 10o tially as described.

3. In a cultivator the combination with the standard having its lower end bifurcated, of

a tooth -holding clip comprising a tooth-en' gaging plate adapted to engage the front face of the bifurcated standard, the clampingwasher for engaging the rear face of the standard and the clampin g-bolt,substantiall y as described.

4. In a cultivator, the combination with the standard having its lower end bifurcated, of the to0th-ho1ding clip comprising the toothengaging plate for engaging the front face of the standard, provided with a stud adapted to enter a recess in the tooth, or shovel, the

.clamping-washer for engaging the rear face of the standard and the clamping-bolt, substantially as described.

5. In a cultivator, the combination with the standard having its lower end bifurcated, and

the said bifurcated portions notched on their rear sides, of the tooth-holding clip comprising the tooth-engaging plate, forengaging the front face of the standard, and provided with a lug adapted to enter a recess in the tooth, the clamping- Washer for engaging the rear face of the standard and provided with projections to engage said notches and the clamping-bolt passing through said tooth, plate and Washer and lying between the bifurcated portions of the standard, substantially as' described.
